Measure the space on your board and the lead spacing\u003cbr\u003e\n  before buying.\u003cbr\u003e\n- **Mind the voltage margin.** 25V suits 12V and 18V rails. On a 24V rail it's\u003cbr\u003e\n  marginal – step up to a 35V or 50V part.\u003cbr\u003e\n- **Use low-ESR for switch-mode supplies.** General-purpose caps overheat and\u003cbr\u003e\n  fail early on the output of a switching regulator.\u003cbr\u003e\n- **Mind the polarity.** The striped leg is negative. Reverse connection\u003cbr\u003e\n  damages the cap and can make it vent.\u003cbr\u003e\n- **Inrush matters.** Several thousand µF across a supply draws a large surge\u003cbr\u003e\n  at switch-on – size your rectifier and fuse accordingly.\u003cbr\u003e\n\u003cbr\u003e\n### FAQ\u003cbr\u003e\n\u003cbr\u003e\n**Why so few values compared with your 50Pcs kit?**\u003cbr\u003e\nThis kit covers the high-capacitance end only. If you need the smaller values\u003cbr\u003e\n(100–470uF), see the 50Pcs 25V assortment instead.\u003cbr\u003e\n\u003cbr\u003e\n**Can I parallel two caps to get more capacitance?**\u003cbr\u003e\nYes. Two 2200uF in parallel give 4400uF and halve the ESR – a common trick\u003cbr\u003e\nwhen a single cap won't fit the height available.\u003cbr\u003e\n\u003cbr\u003e\n**Can I use a 4700uF where the board had 2200uF?**\u003cbr\u003e\nElectrically yes, provided the voltage rating is met and the body fits. The\u003cbr\u003e\nlarger value charges slower and pulls more inrush current at switch-on.\u003cbr\u003e\n\u003cbr\u003e\n**Are they really wrapped separately?**\u003cbr\u003e\nYes – each value comes in its own labelled wrap * \u003cbr\u003e\n\u003cbr\u003e\n### Package Includes\u003cbr\u003e\n\u003cbr\u003e\n- 20 × 25V radial electrolytic capacitors (4 values × 5 pcs)","brand":"DIYMars","offers":[{"title":"Default Title","offer_id":53517109625143,"sku":"CB172091","price":6.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/5562\/4503\/files\/57_40d57a2c-2224-472e-98d4-64b7b63f587a.jpg?v=1793845070","url":"https:\/\/www.diymars.com\/products\/25v-electrolytic-capacitor-kit-20pcs-hiuf","provider":"DIYMars","version":"1.0","type":"link"}
